Tachycardia itself is a heart rate that exceeds the normal range, generally a heart rate of over 100 beats per minutes. A Tachycardia can be caused by a number of factors which are usually benign. But some types of tachycardia, like ventricular tachycardia, can be dangerous due the speed ...
To be classified as tachycardia, the heart rate is usually at least 100 beats per minute. Description A rapid heart rate can originate in either the left or right ventricle. Ventricular tachycardia which lasts more than 30 seconds is referred to as sustained ventricular tachycardia. A period of...
Ventricular tachycardiais the occurrence of three or more beats from a ventricularectopic pacemakerat a rate of more than 100bpm (Malone, 2006; Watchie, 2010; Hillegass, 2011). The ECG findings are wideQRS complexesbecause of aberrant conduction, heart rates greater than 100bpm (usually 150–...

Ventricular tachycardia (VT) is a potentially life-threatening arrhythmia originating in the cardiac ventricles. VT usually results from underlying cardiac diseases, such as myocardial infarction o...
This study was designed to compare QT dispersion measured from the standard 12-lead electrocardiogram and 24-h heart rate variability in patients with vulnerability to either ventricular tachycardia or ventricular fibrillation after a previous myocardial infarction. Increased QT interval dispersion and reduce...
10 s of 12-lead ECG recording were obtained with the EP system and then the animal was paced out of the rhythm using the ICD antitachycardia pacing algorithms. If burst pacing failed, the animal was shocked internally from the ICD. If VF was induced, the animal was immediately shocked ...

Catecholaminergic Polymorphic Ventricular Tachycardia is a rare ion channelopathy characterized by polymorphic ventricular tachycardia during exercise despite a structurally normal heart. Untreated, it has a high risk of sudden death, and delays in clinical diagnosis are common, as t...
